For a desktop PC you're still better off with a 2.5-inch SSD, they're cheaper and generally still faster. However, for laptops with mSATA slots, mSATA SSDs are the perfect solution since you can then use the 2.5-inch bay for storage. It's a great way of improving performance, the best way actually. We can definitely recommend the Plextor M5M 128GB, and we hope that this market will expand in the coming months so there's more choice out there.
